PHP-Handbuch: Increment item's value

Beschreibung

int Memcache::increment ( string $key [, int $value = 1 ] )

Memcache::increment increments value of an item by the specified value. If item specified by key was not numeric and cannot be converted to a number, it will change its value to value. Memcache::increment does not create an item if it doesn't already exist.

Hinweis:
Do not use Memcache::increment with items that have been stored compressed because subsequent calls to Memcache::get will fail.

Also you can use memcache_increment function.
